DwieHr 1B. MONAMEE, or HEMAN, OKLAHOMA.

To all whom t may concern;

Be it known that I, DWIGHT B. MCNAMEE, a citizen'of the United States, residing at Hernan, in the county of Woods and State of Oklahoma, have invented certain `new and usefulImprovementsin Envelops, ofV

which the following is a specification, reference'being had to the 'accompanying`draw ings.

This invention relates to an improved envelop, and has for its primary object to provide an envelop particularly designed for the transportation of valuable papers or currency through the mails, whereby sewing ofthe latter to the paper envelop or con-- tainer is obviated. i

It is another object of my invention to provide an envelop for the above purpose constructed from a single blank sheet of paper foldedupon itself insuch manner as to completely inclose the contents, `and provided with tie strings having one of their ends so fixed to one wall of theA envelop as to be inaccessible, the tie strings being adapted to be tied together and sealed and cooperating with an exterior closure flap so as toprevent the latter being opened and subsequently resealed.

ttis a further object of the invention to provide a device for the -above purpose which is exceedingly siinplein` its construetion, convenient and serviceable in practical use, and `capable ofA manufacture at relatively small Cost.

With the above and otherobjects in view, my invention consists in the novel features of construction, combination` and arrangement of parts to be hereinafter more fully described, claimed and illustrated in the accompanying drawing,rin which,

Figure 1 is a perspective view showing my improved envelop closed;

Fig. 2 is a longitudinal section;

Fig. 3 is a fragmentary interior elevation showing the manner of attaching the tie strings; and

Fig. 4 is a plan view of the blank from which the envelop is formed.

Referring in detail to the drawing, 5 designates the paper sheet which is of any desired texture so as to withstand rough handling, said sheet being cut in the form shown in Fig. 4 of the drawing to provide a front wall 6 at one end of which the sealing flap 7 is formed, said flap being gummed on one side along its edges, as

to therlosure fiap 7 and adapted to be folded over together with the flap, upon the section 11 of the back wall of the envelop. At the opposite end of the blank, the

walls 6, 10 and 11 are also creased, as at 12, and the wall 11 is cut away, as at 13, so thatthe' end portion thereof may fold upon the inner face of said wall 11.

rThe lower end portions below the crease 12 of the walls 6 and 10 are adapted to be folded upwardly upon the wall 1() and secured to'said wall by means of a metal clip or fastener 14- having spurs or teeth indicated at 15 penetrating through the superposed paper layers and being clenched thereon. The wall 10 and the folded end portions of the paper sheet are provided with coinciding openings 16. The foldable flap of the wall 11 and the body of said wall are also provided with similar openings 17 to coincide with the openings 16 when the wall 11 is folded over upon the wall10.. A tie string 18 is securely fixed the envelop by means of a second metal clip 21 which secures a second tie string 2O to the inner face of the wall 10. These walls 10 and 11 and the foldable upper end of the velop will be readily understood from reference to Fig. 1 of the drawing. The envelop, when manufactured for sale, may be folded and the walls thereof fastened together by means of the clips 14 and 21, or the parts of the envelop may be fastened together by the individual user. 1n any event, it will be understood that the papers, currency, or

llt)

other matter to be mailed is inserted into the open end of the envelop between the Walls 6 and lO thereof and the flap then foldedV over upon the Wall or section l1 along vthe crease 9, `the tie string 19 being inserted through the aperture in the closure` Hap.;A The Vguinmed edge ofthis iap is, of course," inoistened so that it will tightly adhere ,to.:

applied thereto to 'confine the 'connected strings upon the` point of the closure flapv 7 and the rear Wall l1 of the envelop. lVith the envelop closed and sealed in this: manner, it Will be readily seen that it Will be iinpossible for the envelop lobe fraudulently opened Without detection. Any attempt to lift or raise the closure Hap 7 would result in breaking the seal of the tie strings.

From the foregoing description,taken in connection vfith the accompanying drawing, the construction, manner of use and several advantages of my improved safety envelop will be clearly and fully understood. The device being of very simple construction may obviously be manufactured at very small cost and affords a complete protection tov documents, currency, or other matt-er Whichis transported through the mails. By means of my device, the necessity of sexving the papers or currency to the Walls of the envelop is entirely obviated and Vdanger of pilfering'is reduced to a minimum. The envelop may, ofcourse, be made in various sizes and .is also susceptible of various modi.- flcations in its several features. I, therefore, reserve the privilege of resorting to all suoli legitimate changes as may be fairly embodied Within the spirit and scope of the invention as claimed.

Having thus fully described my invention, what l desire to claim and secure by Letters Patent is:

1. A safety envelop consisting of a flexible sheet of material folded tol provide a front Wall and inner and outer rear Walls, said Walls having foldableend portions to close Ytheenvelop at one of its ends, a closure flap inthe opposite end1 of! the front Wall7 metal Y fasteners permanently securing the inner and'outer rear Walls to each other, sealing "strings fixed by said fasteners 2upon the inner face of said inner rear Wall, said Walls havingopeningsithrough Which said strings eXtend,said closure flap also having anV opening throughvvhich one ofthe, .strings 4is adapted Yto,be.disposed, sa-id strings being adapted: tol betied together and fixed Ato the thefastenerl said inner Wall and the folded end of the sheet having openings through which said tie string extends and vsaid vouterV rear Wall also having an; opening therein through which the :string is disposed, a second metal fastener securing the inner and outer rear vvalls together adjacentfthe op-- posite end ofthe envelop, the front ivall at the latter end and the envelop being provided With a closure iapsaid flap landthe front and rear Walls having openingstherein, and a secondisealingstring secured ,to the inner face of the inner rear wall byl the second named fastener to extend,through said openings and adapted tobe tiedto the iirst named sealing string and said strings securedlby a suitable'sealing material to the rear Wall and the closure flap of the envelop. In testimony whereof I hereunto affix my signature in the presence of two Witnesses.
